Very odd. When executing from the Makefile script, `svn` kept
complaining about APR not being compiled with threading support
(because it picked up the APR in ~/svn/prefix), but when I executed
the same command plainly from command-line, it worked fine.

Hm, but I didn't have LD_LIBRARY_PATH set. That's what's odd. The
trunk svn works fine -- when I add ~/svn/prefix/svn-trunk/bin to
$PATH, `svn` picks up the right APR and just works.

Thanks for the help in diagnosing the problem -- I'll read a little
more about the Linux linker's behavior and try to find out what the
real problem is.
